Concrete Floors above D.P.C. level

Cover concrete floorslab with a suitable damp proof membrane, ensuring adequate coverage at joints. Membrane should be taken up vertical surfaces to finished screed level.

KIMMCO Building Slab is laid directly on top of the damp proof membrane with edges close butted and joints staggered. Edge insulation consisting of strips of insulation not more than 2.5cm thick cut from standard slab with a width to suit the specified screed thickness should be placed vertically against the walls, the bottom edge resting on top of the horizontal and vertical insulation with care taken to ensure that laps are well covered. It is recommended that the screed should be 60mm thick with a galvanised mesh reinforcement laid into it.  

Cavity Walls

Use gavanized, stainless steel or nylon hangers with retaining washers for holding the insulation in correct position.

The 2” FSK overlap of KIMMCO Building Slab to be positioned at the bottom of each slab in order to cover the top of the underlying slab to protect the insulation from accidental water spilling during the outside wall construction.  

Solid Wall Construction

b) Apply foil faced KIMMCO Building Slab to the wall with recognised mechanical fastenings such as Hilti using large head washers. Insulation should be applied with staggered vertical joints. All boards to be close butted. Apply expanded metal, galvanised chicken mesh or plastic netting over the insulation using mechanical fasteners. External rendering or other facing can now be applied.

c) KIMMCO recommend that metal wall ties or wires be used to tie the external wall ties or wires be used to tie the external wall finish (marble or stone) to the internal wall. This gives additional stability to the structure. Care should be taken to ensure that the wall ties are long enough to reach from the internal wall through the insulation to the external finish.

Joints: KIMMCO recommended that where vapour barriers are used, all joints

Concrete Roofs

The roof surface should be clean and dry. A perfectly smooth surface to the concrete is not necessary but care should be taken to ensure the boards do not rock.

KIMMCO Building Slab should be bedded in a bitumen compound on top of an approved continuous vapour barrier with well lapped joints. Weathering treatments should be laid in accordance with manufacturers instructions. A reflective surface finish should be applied to reduce absorption of solar heat.

KIMMCO Building Slab can used with Synthetic membranes by sticking, in accordance with the membranes manufacturers specifications.  

Metal Roofs

KIMMCO Building Slab may be applied to metal roof decks by bitumen adhesion or by mechanical fixings. For bitumen compound on top of a continuous vapour barrier. Care must be taken to ensure that joints between boards are supported by the deck profiles and are not laid with the open flutes running continuously beneath. It is recommended that the insination be placed at a 45 deg. angle to the line of the deck flutes.

For Mechanical fastening one of several methods may be used i.e. Lexscuco clips or screw and washer, fixings. Washets should be 50 mm in diameter with a large countersink cup so that screw heads do not protrude above insulation.  

Falls Ceiling

Falls should be incorporated in roof deck construction by contractor.

Access Roofs

KIMMCO Building Slab laid directly beneath weather proofing such as built up roofing is suitable for roofs carrying normal light maintenance traffic. Where continuous foot traffic is expected a finish of concrete tiles or similar should be applied.

Building Slab should not be used for roof decks where heavy point loadings can be expected or where vehicles of any type will be used.
